Observations of a black hole X-ray binary indicate formation of a magnetically arrested disk
Bei You, Xinwu Cao, Zhen Yan +8
Accretion of material onto a black hole drags any magnetic fields present inwards, increasing their strength. Theory predicts that sufficiently strong magnetic fields can halt the…
Formation and evolution of transient jets and their cavities in black-hole X-ray binaries
Marek Sikora, Andrzej Zdziarski
We propose a model explaining the origin of transient/episodic jets in black-hole X-ray binaries, in which they are caused by transitions from a collimated, strongly magnetized, je…
No Need for an Extreme Jet Energy in the Black-Hole X-Ray Binary MAXI J1348--630
Andrzej A. Zdziarski, Marek Sikora, Michal Szanecki +1
We model interaction with the surrounding medium of the main discrete jet ejection in the accreting black-hole binary MAXI J1348--630. The kinetic energy in the ejection of that je…
A simple analytical model of magnetic jets
Andrzej A. Zdziarski, Lukasz Stawarz, Marek Sikora +1
We propose a simple analytical jet model of magnetic jets, in which radially-averaged profiles of main physical quantities are obtained based on conservation laws and some results…
The Composition and Power of the Jet of the Broad-Line Radio Galaxy 3C 120
Andrzej A. Zdziarski, Dakalo G. Phuravhathu, Marek Sikora +2
We calculated the electron-positron pair production rate at the base of the jet of 3C 120 by collisions of photons from the hot accretion flow using the measurement of its average…
The dependence of the fraction of radio luminous quasars on redshift and its theoretical implications
Katarzyna Rusinek-Abarca, Marek Sikora
While radio emission in quasars can be contributed to by a variety of processes (involving star forming regions, accretion disk coronas and winds, and jets), the powering of the ra…
